Scotch Blue is from the Colour by Nature palette, created in collaboration between Farrow & Ball and the Natural History Museum. It\'s the darkest blue in the Farrow & Ball palette and more intensely coloured than the blue-based black shade Railings, making for eye-catching woodwork or a deeply luxurious wall colour. Try it in Estate Emulsion for a particularly velvety feel.Modern Eggshell is Farrow & Ball\'s toughest interior finish, adding colour and protection to wood, metal, and concrete surfaces. This ultra-durable eggshell is tough enough for floors, and it can also be used throughout the home on skirting, doors, kitchen cabinets, furniture, and radiators.
